High-fluidity environment-friendly ultrahigh-performance concrete and preparation method thereof
The invention discloses high-fluidity environment-friendly ultrahigh-performance concrete. The concrete is prepared by mixing low-heat Portland cement, fly ash microspheres, silica fume, fine sand, quartz powder, a water reducing agent, water and steel fibers according to a certain ratio. Pollution is produced during production of cement; however, waste fly ash microbeads of a thermal power plantare adopted to replace a part of cement in the invention, so pollution reduction and environmental protection are realized, and the obtained ultrahigh-performance concrete has very good working performance, relatively small shrinkage and relatively good crack resistance, and is convenient to construct; and compared with existing ultrahigh-performance concrete with the same water-binder ratio, glue-sand ratio and steel fiber mixing amount, the ultrahigh-performance concrete has the advantages that working performance is greatly improved, and the problem of poor working performance of the existing ultrahigh-performance concrete can be solved, so the ultrahigh-performance concrete has good economic benefits and environmental protection benefits and is suitable for large-scale popularization and application.
本发明公开了一种高流动性环保型超高性能混凝土，其是由低热硅酸盐水泥、粉煤灰微珠、硅灰、细砂、石英粉、减水剂、水和钢纤维按一定比例混合制得。水泥在生产过程中会产生污染，本发明采用火电厂的废料粉煤灰微珠替代部分水泥，有利于减少污染，保护环境，所得超高性能混凝土具有很好的工作性能、较小的收缩和较好的抗裂性能、施工方便；与相同水胶比、胶砂比、钢纤维掺量的现有超高性能混凝土相比，本发明超高性能混凝土的工作性能有很大的提高，可解决现有超高性能混凝土工作性能较差的问题，因此具有良好的经济效益和环保效益，适合大规模推广运用。
